class FLandscapeTextureMipEdgeOverrideProvider : public FTextureMipDataProvider

Name	Remarks	Include Path	Unreal Specifiers
FLandscapeTextureMipEdgeOverrideProvider ( ULandscapeHeightmapTextureEdgeFixup* InEdgeFixup, UTexture2D* InTexture )	This class is actually a "Modifier" in that it doesn't provide any mips, it only modifies mips provided by the default providers It relies on some assumptions about the existing provider execution that are currently true, but may not remain true forever: 1) that all providers are executed, even if they are not actually handling any mips 2) that all default providers do NOT modify mip data in PollMips (this is true for both FTexture2DMipDataProvider_IO and FTexture2DMipDataProvider_DDC currently) this allows us to modify mip data in PollMips and not worry about being stomped on. IF either of these cease to be true, we should probably write a first class FTextureMipDataModifier path, and convert this to be a modifier instead of a provider.	LandscapeTextureStorageProvider.h
